Specification forming part of Letters Patent No. 220,488, dated October14, 1879; application filed March 19, 1879.

To all whom it may concern.-

Be it known that 1, ROBERT C. MORRIS, of Olney, in the county ofRichland and State of Illinois, have invented certain new and usefulImprovements in Sheet-Metal Vessels; and I do hereby declare that thefollowing is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to letters of reference marked thereon, which form a part of thisspecification.

Figure l is a perspective view of a sheetmetal vessel, showing theexterior thereof, and

also a portion of the interior, together with a portion of the jointcaused by uniting the two ends of the sheet which constitutes thecylindrical portion thereof; and Fig. 2 is a sectional elevation,showing the method of constructing the cylindrical portion, and also thebottom or head, and of attaching them together.

Corresponding parts are designated by like letters in both of thefigures.

This invention relates to vessels which are made of tin and other kindsof sheet metal, the object being to provide such vessels with a bottomthat shall not be exposed to wear when they are standing on their ends;and, further, to protect them against leakage when one thickness of themetal composing the surface which rests upon the ground or othersubstance has been worn away; and it consists in combining, with thebody of a sheet-metal vessel having formed upon its end or ends aninwardly-projecting double flange or ledge, a head having upon itsperiphery or outer edge two thicknesses of metal, said head being madeto rest upon and being soldered to the flange or ledge upon the body ofthe vessel,

as will be more fully described hereinafter.

In constructing vessels of this character I use sheet-tin or any othersuitable kind of sheet metal, and they may be made of any required formand dimensions that will adapt them to the purposes to which they are tobe applied.

The vessel shown in the drawings is cylindrical in form and is supposedto be made of tin, A representing-a eylindermade from a turned inwardand then sheet of such metal, its ends having been joined together inthe usual or any approved form. As will be seen by referring to thedrawings, the lower edge of this cylinder is outward, theoutwardly-turned portion resting upon that portion which extends inward.This form of construction provides aledge or base for the head or bottomof the vessel to rest upon, and at the same time strengthens the vesselat that point,while it protects the head or bottom from wear, andprovides a means of keeping the vessel tight even after the outerthickness of metal has been worn away, the solder used in securing theparts to each other effecting such purpose.

The bottom or head B of the vessel is of circular or other form thatwill cause it to fit the vessel in which it is to be placed. Upon theperiphery or edges of this head a flange is turned, the width of whichshould be about equal to that of the inwardly-projecting ledge upon thevertical portion of the vessel. This flange, like that upon the part A,is bent in such a manner that its inner surface rests upon the outersurface of the ledge of the head, the diameter or dimensions of whichare such as to allow it to be put into the end of the ves sel oppositeto the one upon which the flange is turned, and pressed downward untilit rests upon the ledge formed thereon, when the two are solderedtogether, by preference, both upon their inner and outer surfaces.

I have described the head of this vessel as having a flange turned uponit, which'l regard as the best method of constructing it; but it is truethat when small vessels are being made, or when metal of sufficientthickness is used, a plain disk of metal without a flange may be used.This method of construction is applicable to milk-cans, pans, and allforms of vessels used for portable purposes.

I am aware that inwardly-projecting single flanges or ledges formed uponthe bodies of sheet-metal vessels have heretofore been used, such, forinstance, as are shown in the patents to William A. Wicks, grantedFebruary 29, 1876, No. 174.334, and U. D. Alexander, April 28,1875, No.162,454, and in a patent granted nesscs of metal, said head resting uponand being soldered to the flange or ledge formed upon the body of thevessel, substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I afiix my signaturein presence of two witnesses.

ROBERT C. MORRIS.
